Agriciltural microbiology| Summary: | The paper covers the results of the orientation of different biological processes (nitrogen fixation, N2O and CO2 emissions) in the root zone of potato plants under the different fertilization systems in a field experiment in stationary experiment on leached black soils. The application of 40 t/ha of cattle manure was shown to be more environmentally beneficial (although with some caution, due to the high level of N2O emissions). The N40P40K40 dose of fertilizers was shown to be optimal, while the balance between environmental requirements and crop productivity shows the practicability of application of N80P80K80. High doses of fertilizers (N120P120K120) and organic mineral fertilization (40 t/ha manure + N80P80K80) had resulted in high levels of N2O and CO2 emissions and reduced nitrogen fixation activity. Application of biological preparation Biogran was shown to be efficient in the potato growing technology due to its proved ability to optimize the ecological condition of soils in agrocoenoses, increase productivity and improve the quality of potatoes. |
